To all whom it may concern Be it known that We, Tnnononn DAN- HEIsnR, a. citizen of theUnited Suites and o resident of the borou h of Manhattan, in the city and State of ew York, and Fernnmon FRANCIS FECHER, a citizen of the United States, and o resident of the borough of Brooklyn in the city and State of New York, have invented certain new and useful improvements in Duplicators, of which the following is specification.

The invention relates to duplicotors more perticuluriy to that form of duplicetorin which a negative or reversed impression of matter to he copied is impressed upon it duplicating surface and positive impres sions taken therefrom by bringing sheets of paper or the like contact therewith; has for one of its principal objects to pro vide simple and comparatively cheep inc-ens whereby the rapid handling of said sheets of paper is facilitated, this application he ing :1 division of epplicstionhlo. iconic, filed October ll, 1917.

The invention consists in the novel construction, arrangement and comhinution of vorious devices, elements and ports, us set forth in the claims hereof one form of the some being shown in the accompanying drawings and hereinafter more particularly described.

in the seid drawings, Fig. 1 is at side view of one embodiment of our invention; Fig. 2 is it longitudinal vertical section token on the line 2-2 of Fig. 3 and looking in the direction of the arrows; Fig. 3 is an end View looking from the left of Fig". 1; end Figs. 4:, 5 end 6 are views of the portion oi the apparatus shown at the left of Fig. 2, showing the ports in various positions.

In carrying our invention into effect in the embodiment thereof which we have selected for illustration in the accompanying drawings and description in this specifics.- tion. we provide a. duplicator of the usual or any suitable type, such as may comprise a hose 11 having mounted thereon :trsrne members 12., in which are suitably removehly journnled roliers 13 upon which n duplicating" film id is adopted to he wound.

The duplicating film l tpesses upward and over a. hed 16 secured hetween the n einhers 12 rollers edjscent the ends of this bed heing adopted to prevent the film from screp retelnets and devices 20 edopted,'when desired, to hold seid pswls out of operation; all of which means are now known in the art and need not. be described in detail. it is thus possible to bring any portion of the duplicating film wound upon the rollers 13 into operative position over the bed 16, and

to stretch the some tightly thereover.

A paper support or table is slidahly mounted on the duplicator by means of flanged members &3 attached to said tohle {see 3). The table comprises a bottom 40, on end 4:1 end sides 1-2 projecting beyond the left hand end of the bottom 40 as shown in Figs. 1 end 2. Pivot/ed st 43 in the free ends of these sides 42 is e. ti-shuped frame it provided with a handle to, and having on impression roller 4L6 iournsled in its lower end.

At one side of the frame td is secured a loterelly extending finger 47. A paper support or shelifdS is pivoted st points 49 on the ironic it, end is provided on one side (see Fig. l) with e. slotted arc-member 50 til hy means of which its position may be adjusted, the member 50 being secured in any position desired by means of a screw or the like 5%. A paper depressing member 51 is secured to the frame to, which depressing member 51 may if desired be, but is not necesserily s rolier. vided for the purpose of restricting the op erctive ores of the bottom 40 of the paper support or tehle.

in the operation of this embodiment of our invention, the uttachment losing in place upon the duplicator end the ports in the position shown in Figs. 1 end 2, 9. sheet of pep-er heurin g the matter which it is desired to copy is pieced face downwerd, upon the tnhle, and upon this are placed any desired numher of sheets of paper upon which it is desired to copy the mutter tronsierred Means to may he pro- Sitltl pressing moved.

so that one end of the pile shall rest upon the support 48', the devices 52 being adjusted in the proper manner. The handle 45 is then moved toward the right in Fig. 1, until the devices occupy the position shown in Fig. 4. When in this position the finger 47 enters a depression 153 in the bed 16, or may clear the end of the said bed, and the demember 51 forces the pile of paper downward, so that the sheet on the bottom of the pile will be brought into contact with the duplicating surface and will adhere thereto. The parts are then moved into the position shown in Fig. 5, leaving the sheet on the bottom of the pile adhering to the duplicating surface at one end, the remaining sheets being in their original position. The handle 45 being held in the position shown in Fig. 5, the attachment as a whole is moved toward the right in Fig. 1, withdrawing the undermost sheet of paper of the pile from the support or table, and bringing same into contact with the-duplicating medium, whereby an impression is transferred from said sheet to said medium by means of the impression roller 46. After the attachment has been moved to its extreme right hand position, and approximately all of the paper has been passed over by the impression roller, the handle 45 and attached parts are moved into the position relative to the horizontal shown in Fig. 6, in which position the impression roller d6 is raised above the paper, enabling the said paper to be relhe handle 45 being held in the position shown in Fig. 6, the attachment is returned to its original position, the finger e7 bearing upon the bed 16 and holding the paper depressing memberfil out of contact with the duplicating medium. The attachment being returned to the position shown in Fig 4:, the process may often as desired, in this case, however, resulting in transferring impressions from the duplicating medium to the blank sheets of p p i The advantages of our invention will be obvious. We may particularly enumerate the cheapness of construction, the ease of operation, and the fact that each impression will be printed upon the same relative portion of its respective paper. We do not limit ourselves to the exact form described, as it will be evident that various other modifications might' be made, without departing from the'spirit and scope of the said invention.

Having thus described our 'invention, what we claim as new and desire to secure by Letters Patent is as follows:

1. An attachment for duplicators adapted to bemovably supported thereon and comprisi means adapted to support parts of a plurality of sheets of paper or the like and to permit a part of the lower of said sheets be repeated as i ,eaaeae to be depressed on the said duplicator and adapted when moved with reference to said duplicator to permit said lower sheet to escape but to retain all the other said sheets; said attachment also comprising means adapted to so depress said paper.

2. An attachment for' duplicators comprising a paper supporting member adapted to be movably mounted over a duplicator, and a frame secured to said paper supporting member, said frame being provided with a paper depressing member and with an impression device.

3. An attachment for duplicators comprising a paper supporting member adapted to be movably mounted over a duplicator, and a frame pivotally secured to said paper supporting member, said frame being provided with a paper depressing member and with an impression device, said'impression device and said depressing member being lo- .catedon opposite sides of said pivotal point.

4. An attachment for duplicators comprising a paper supporting member adapted to be movably mounted over a duplicator, and a frame secured to said paper supporting member, said frame being provided with a paper depressing member, an impression device, and a laterally extending finger adapted when said frame is in one position to come in contact with a portion of said duplicator, and when said frame is in another position to clear said duplicator.

5. The combination with a duplicator comprising a duplicating medium adapted to receive an impression and to transfer same;

of a member movably supported on said duplicator comprising means adapted to support the marginal portions of a plurality of sheets of paper or the like and to permit a portion of the lower one of said sheets intermediate said marginal portions to be depressed into contact with said duplicating medium and adapted when moved with reference to said duplicating medium to permit said. lower sheet to escape but to retain all the other said sheets; and devices adapted to depress a portion of said paper into contact with said duplicating medium.

6. The combination with a duplicator; of an attachment therefor comprising'a paper supporting member adapted to be movably mounted over said duplicator, and a frame secured to said paper su porting member, said frame being provide with a paper depressing member and with an impression device.

7. The combination with a duplicator; of an attachment therefor comprising a paper supporting member adapted to be movably mounted over a] duplicator, and a frame pivotally secured to said paper supporting member, said frame being provided with a paper depressing member and with an impression device, said impression device and maaeaa said member being located on opposite sides of said pivotal point.
